Abstract
Applications of plant growth regulators in late August effectively terminated the fruiting of cotton and significantly reduced populations of diapausing larvae of Pectinophora gossypiella (Saunders) (by 90% or more) in Arizona during 1972–74. As a result, fewer overwintered moths (39%) emerged the following spring from terminated plots. Applications in mid-, or late August were more effective than applications in early September. Yields were not significantly reduced by most treatments. The most effective materials tested were 2.4-D (amine salt of 2,4-dichlorophelloxy) acetic acid + chlorflurenol (methyl 2-chloro-9-hydroxyfluorene-9-carboxylate) and 2, 4-D + chlormequat ((2-chloroethyl) trimethylammonium chloride).
